Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
The structured flowchart of the front handling mobile crane intelligent car-backing BAS first embodiment proposed for this utility model shown in Figure 1.As it can be seen, the proposed aid system of the present embodiment includes signal gathering unit 1, control unit 2, motor 3, electric pushrod 4 and brake pedal 5.Wherein signal gathering unit 1 includes laser radar sensor 11, gear signal testing circuit 12 and rate signal testing circuit 13.Shown in Figure 2, laser radar sensor 11 is arranged on the rear side of front handling mobile crane 8, to identify the barrier on rear side of front handling mobile crane 8.According to the actual requirements, laser radar sensor 11 can arrange one, or is symmetrical arranged a pair laser radar sensor 11 on rear side of front handling mobile crane 8, it is achieved to 180 degree of detections of barrier on rear side of front handling mobile crane 8.Laser radar sensor 11 detects the size of barrier, and polar coordinate position information dyspoiesis analyte detection signal.Specifically, the barrier origin pole coordinate that laser radar sensor 11 returns according to pick-up, set up the two-dimensional coordinate system being initial point with hull back center, dyspoiesis analyte detection signal also exports to control unit 2.
Signal gathering unit 1 is additionally provided with gear signal testing circuit 12 and rate signal testing circuit 13.Gear signal testing circuit 12 detects the real-time gear in front handling mobile crane driving process and generates gear detection signal and export to control unit 2, and rate signal testing circuit 13 detects the real-time speed formation speed detection signal in front handling mobile crane driving process and exports to control unit 2.The input of control unit 2 receives one or more in obstacle detection signal, gear detection signal and speed detection signal.Control unit 2 preferably receives obstacle detection signal, gear signal and rate signal simultaneously, accurately to detect the real-time distance between front handling mobile crane and barrier.
Control unit 2 is preferably programmable logic controller (PLC), it is possible to use can realize the single-chip microcomputer of said function, integrated circuit or controller, in this no limit.If the real-time distance between front handling mobile crane and barrier belongs to safety range, control unit 2 generates actuating signal and exports to motor 3.Motor 3 receives actuating signal, drives electric pushrod 4 to stretch out, discharges brake pedal 5, driver can normal operating, drive front handling mobile crane.
If barrier is in deathtrap, control unit 2 generates actuating signal and exports to motor 3, and motor 3 receives actuating signal, drives electric pushrod 4 to bounce back, strains brake pedal 5, it is achieved brake hard.
Being additionally provided with alarm device 6 in front handling mobile crane reversing BAS, when barrier is in deathtrap, control unit 2 generates and output switching signal is to alarm device 6, and alarm device 6 receives described switching signal and reports to the police.Specifically, alarm device 6 includes the buzzer 62 that is arranged in driver's cabin, it is also possible to arrange alarm lamp 61 accordingly.
Being additionally provided with on-board screen 7 in driver's cabin, on-board screen 7 receives the obstacle detection signal of laser radar sensor 11 output and shows.Can also arranging reverse image device on rear side of front handling mobile crane, on-board screen 7 receives the picture signal of reverse image device generation simultaneously and shows, to help driver to know whether front handling mobile crane rear has barrier, improves the safety coefficient of operation.
Front handling mobile crane is when the operation of case district, station, it is contemplated that travel speed, safer when the distance between front handling mobile crane distance barrier is more than 6 meters, then comparatively dangerous when distance is less than 1 meter.Therefore, deathtrap can be divided into three grades by warning level.When danger early warning rank is in three grades, control unit 2 output switching signal is to alarm device 6, and buzzer 62 is reported to the police with comparatively mild sound.When danger early warning rank is in two grades, control unit 2 output switching signal is to alarm device 6, and buzzer 62 is reported to the police with upper frequency.Meanwhile, control unit 2 generates actuating signal output to motor 3 control circuit.The circuit diagram a kind of for motor 3 control circuit shown in Figure 3, is provided with one group of interlocking contact device KA1 and KA2 in motor 3 control circuit.The outfan of control unit 2 is two groups of level signals (H1, L2) of output and (H2, L1) alternately.When H1 exports high level, during L2 output low level, H2, L1 is high-impedance state, and now, automatically controlled push rod stretches out, and brake pedal 5 is released；When H2 exports high level, during L1 output low level, H1, L2 is high-impedance state, and now, automatically controlled pusher retracted, brake pedal 5 is tightened up.Brake pedal 5 stroke is controlled, it is achieved the progressively brake of front handling mobile crane by alternately two groups of level signals of output.When danger early warning rank is in one-level, control unit 2 generates gear signal, makes front handling mobile crane be in power state out of supply, then passes through alternately two groups of level signals of output and controls brake pedal 5 stroke, it is achieved brake hard.Meanwhile, control signal output switching signal is to alarm device 6, and buzzer 62 is with rapid audible alarm, and alarm lamp 61 glimmers.Switch element in motor 3 control circuit is not limited to catalyst, it is also possible to select other switch element to realize same function.Danger early warning rank can also be passed through the parameters such as resultant fault thing distance, speed, gear, brake pedal 5 position and delimit.
The front handling mobile crane intelligent car-backing BAS that the present embodiment is proposed, when there is barrier at front handling mobile crane rear, it is possible to timely automated control front handling mobile crane automatic retarding, braking, efficiently avoid and security incident occurs, intelligence degree is high, and safety can be to be fully ensured.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
